Sonos Amp - alarms behaving erarrtically and streaming stations time looping.

My Sonos Amp has been running well for several years. In about Feb 2026 two issues arose - that may or may not be related.

  1. The existing alarms after working flawlessly for years started to behave eratically, either not turning on at all or turning on and then off again well short of the preset time.

    I have deleted and recreated the alarms but this has not resolved this first issue.
     
  2. When streaming a radio station the output, (at various times seemingly at random), jumps back to where it was about 3 minutes earlier. (if I had to guess I would say the control of the buffer has become unstable) 

    I have (a) restarted my NBN modem, (b) restarted  my wifi router and (C) factory reset the Sonos Amp and readded it back to my system and recreated the alrams but these have not resolved this second issue.

How do I resolve these?  Any suggestions will be gratefully accepted.

Did you have the Sonos unplugged when you rebooted the router?

Please don’t factory reset anything further, unless instructed by a Sonos employee. A factory reset rarely resolves an issue, and is fairly destructive to an existing Sonos system.

Factory Reset destroys diagnostic data that could have been used by SONOS Support to discover the issue.

    I have received the loud and message that I should NOT do a factory reset.😊

     

    I am hopeful that somewone will advise me of remedial action than I can do.

    Sadly Sonos does not make troubleshooting and diagnostic data available to us users, it can be sent to Sonos and then a call to support can have it looked at. They don't look until contacted, so the call is needed.

    If you can submit a diagnostic from the app within a few minutes, sooner is better and beyond 10 is iffy, it will likely capture information that can be used to suggest a remedy.

      I did suggest that the Sonos devices be unplugged while you rebooted the router. You haven’t replied that you’ve previously done so or not.

      Alternately, if you can, I would recommend that you submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it. Don’t post the resulting diagnostic number here. 

      There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

      And even if you can’t run that diagnostic, there is value in making the call, as they have access to additional information that we in the public don’t. 

      When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.
